@Yurik "Yes, the rules are slightly different, but I doubt there will be many fundamental disagreements about the data." How do you know this for sure? I can think of several cases off the top of my head where it would be different. Take California state highways: sometimes the road still exists, but is no longer a state highway. One of the fundamentals of good programming is accounting for corner cases, rather than trying to shoehorn everything into one paradigm/user story.
